XER Screen ink (High Quality and High Definition Screen Printing Ink for Nameplate)

High Quality and High Definition screen printing ink is the ink which reproduces solid printing and fine pattern faithfully and enables stable printing of 100µm width fine line with quite high accuracy.  Ink sagging width: Within 8µm (one side), within 116µm (line width).
Excellent printing stability and re-printability, which number of times of stencil cleaning can be reduced.
XER ink is one pack type screen ink which is suitable for printing fine line or characters on name plate, etc., and provides printed ink layer with excellent flexibility and heat resistance at post-processing.

Note) Now we still deliver High Definition Ink in Japan only.

Application

  • Pattern-printing on PET film with treatment for easy adhesion, PC film and sheet.
  • Be sure to confirm before use if annealing (preheat) is required depending on materials.

Special features

  • Enables quite highly-precise printing such as printing 100µm width fine line, dot, etc.
  • Excellent printing stability and high-speed printability.
  • Printed ink layer provides excellent adhesion property.

Thinning / Cleaning

  • Stir well before every use.
  • Thinning is not required before printing. Add XZ-705 Solvent within 5 % if necessary.
  • Screen Cleaner XN is recommended to clean the stencil.
  • XSM-40 Defoamer can be added up to 1% for defoaming and improving leveling property.

Printing

  • Refer to the printing specification sheet for printing conditions.
  • Coverage of 971 Black with 350 mesh would be about 80 m2/kg.
    (Calculated value of printed ink layer thickness 5 µm)

Drying / Curing

  • Make sure of heated drying. Standard tack free time is 10 minutes at 80°C in box type dryer.
  • Standard final drying conditions are 80°C for 30 minutes.
  • Drying property may be changed by printing dimensions, stencil mesh, printing environment (temperature, humidity, etc.), and performance of dryer.
  • Test under actual conditions before commercial run is strongly recommended.
